The url() function gives access to the URL of the current page. It does not take any parameters. If, for example, the current page was the “Articles” page, then

<?php echo $this->url(); ?>

returns the value:

http://mywolfsite.com/articles

See also: urlById()

To return the URL of a page that is not current, use the find function. This code:

<?php echo $this->find('articles')->url(); ?>

returns http://mywolfsite.com/articles from anywhere in the site.

Although url() can of course be used for creating links, there is a specialized function that is normally the preferred way of doing this: see the documentation on the link() function.
